Elevator leveling fault detection method and system

Abstract

The invention relates to a detecting method and system for elevator level layer fault. When an elevator car door is opened, a target image of an area where an elevator car interior sill and a landingdoor sill of a floor where an elevator is located are located is obtained, the visual angle difference value between the elevator car interior sill and the landing door sill in the target image is calculated, and when the visual angle difference value is larger than or smaller than a preset value, the elevator level layer fault is determined. In the scheme, the target image of the area where the elevator car interior sill and the landing door sill of the floor where the elevator is located are located is analyzed and calculated, the visual angle difference value between the elevator car interior sill and the landing door sill can be obtained, whether the elevator level layer fault occurs or not is judged according to the visual angle difference value, the hysteresis caused by the fact thata user complains and informs an elevator operation and maintenance person is avoided, after the fault is found, the elevator operation and maintenance person can be informed to repair, operation andmaintenance resources are fully and rationally utilized, and thus the detection efficiency of the elevator level layer fault is improved.

Description

technical field [0001] The invention relates to the technical field of elevator detection, in particular to a method and system for detecting elevator leveling faults. Background technique [0002] During the actual use of the elevator, with the passage of time, the various components of the elevator will gradually age, resulting in component failures, which cannot be used normally, and component failures due to unpredictable factors will affect the normal operation of the elevator. The detection of elevator failure is particularly important. [0003] During the operation, when the elevator reaches the target floor, it needs to level the floor, and the sill inside the elevator car is flush with the sill of the landing door of the target floor, so that people can enter and exit the elevator safely and conveniently. However, elevators that have been used for a long time often have the situation that the elevator cannot be accurately leveled, that is, the sill in the elevator ...
